The abstract talks about the importance of reversing loops of edges, so there are some functions that find loops, some that reverse loops (both right going and left going). Since handleLLoop is not even complete, we may not even be using these functions yet.

    void findReversibleLoop(int e) {       
    void handleRLoop(int e, intList rloop) {
    void handleLLoop(int e, intList lloop) {

These use a bunch of lower-level functions that we ignore for now.

   public void fixinto_ccw(int e, int f) { // reverse edge e, and fix pointers ccw from e to f

   public void fixinto_cw(int e, int f) { // reverse edge e, and fix pointers cw from e to f

// replace an edge in for a ccw triangle with a cw edge out.
  void edge_reverse_ccw(int a, int b) {
                 
// replace an edge in for a ccw triangle with a cw edge out.
  void edge_reverse_cw(int a, int b) {
